Thank's a lot for your kind help! :-)
For my project, I will try a distributed file system like Lustre, PVFS or HDFS, because it is very likely that I will need more than 2 nodes in the future.
Best Regards,
Christian

I know of a few people that are using this setup on 2 node web clusters and it works very well for them. However I don't know if you can run this with more than 2 nodes.
